Passarini’s “Nuove inventioni d’ornamenti d’architettura e d’intagli diversi: utili ad argentieri, intagliatori, ricamatori et altri professori delle buone arti del disegno”, was published as a model book for goldsmiths and craftsmen. It consists of 32 designs for various objects from coaches to reliquaries and coats of arms. Many of the plates represent coaches, reflecting Passarini’s main activity as a coach designer.
